By December 2014 the comet had brightened to roughly magnitude 7.4, making it a small telescope and binoculars target. By mid-December the comet was visible to the naked eye for experienced observers with dark skies and keen eyesight. On 28−29 December 2014, the comet passed 1/3° from globular cluster Messier 79. In January 2015 it will brighten to roughly magnitude 4−5, and will be one of the brightest comets located high in a dark sky in years. On 7 January 2015 the comet will pass 0.469 AU (70,200,000 km; 43,600,000 mi) from Earth. It crosses the celestial equator on 9 January 2015 becoming better seen from the northern hemisphere. The comet will come to perihelion (closest approach to the Sun) on 30 January 2015 at a distance of 1.29 AU from the Sun.
Before entering the planetary region (epoch 1950), C/2014 Q2 had an orbital period of about 11500 years. After leaving the planetary region (epoch 2050), it will have an orbital period of about 8000 years.
